摘要

在本文中，我们将介绍TU单元切换所需的功能，并解释执行这些功能的TUSM(TU11/TU12帧对齐和监督监控)的设计。VC3信号终端、TUT11/TU12信号帧对准和监控功能是实现宽带数字交叉连接系统(BDCS)中具有50 M/150 M电平和1.5 M/ 2m电平交叉连接功能的TU11/TU12单元切换所必需的。芯片的连接速率设置为19.44 Mb/s，具有7个TUG2的信号释放/形成、解复用/复用、28个TU11或21个TU12的帧对准、VC11/VC12信号路径监控功能和位于前后时间开关的信号连接监控功能。

TU11/TU12 signal frame alignment and supervisory monitoring ASIC design

In this paper we will go over the functions required for TU unit switching and explain the design of TUSM(TU11/TU12 frame alignment and supervisory monitoring) which executes these functions. VC3 signal termination, TUT11/TU12 signal frame alignment and supervisory monitoring function are essential to execute the TU11/TU12 unit switching in the BDCS (Broadband Digital Cross-connect System) with the 50 M/150 M level and 1.5 M/2 M level cross-connection function. The connection rate of the chip is set to 19.44 Mb/s and it is designed to have signal release/forming, de-multiplexing/muitiplexing of 7 TUG2, frame alignment of 28 TU11 or 21 TU12, VC11/VC12 signal path monitoring function and the monitoring function of signal connection located at the pre/post time switch.
